l Be it known thatI, STEPHEN-E-C1BULAS,

a citizen .of the United States, residingr at ,j

. 604 Wood A'vel,.Bridgeport, county of Fair- `field, State of Connecticut, have invented Van tion.

shall extend inward but littledistance from the wall of the building and occupy but little "space, and in whichalllateral strain and to a window;

pressure upon the window or windows, at.,

the beginning of .the yopening movement, shall be eliminated, so that there will be no jamming of the windows against the casings,

each window being free to swing at-Aall portions of its movement With these and other objects in view, I have devised thefnovel window Operating mechanism which Il will now describe, r

ferring to the accompanying drawings formlng a part of this specification and using reference characters to indicate the lseveral parts. l I
